Commonly Experienced Problems

LockDown Browser Will Not Install On My Windows or Mac Computer

Did the installation file have an . EXE file extension ?
Some security programs are known to automatically change an executable file's extension from .EXE to .EFW. This prevents the installation file from running. You can resolve this problem by manually changing the file extension back to .EXE. After the installation file's extension is changed back, try installing the file again.

Mac Users: Do you get a "Cannot Configure Application Properties" message when the installation completes?

  1. Run the downloaded installer again.
